Rails: Allows AC or DC Output Coupling
– Supports Driving Two Video Lines/Channel
The THS7365 is an ideal choice for all video buffer
applications. Its rail-to-rail output stage with 6-dB gain
• Low Total Quiescent Current: 20.7 mA at 3.3 V
allows for both ac and dc line driving. The ability to

• RoHS-Compliant Package: TSSOP-20
(disabled mode) makes it an excellent choice for
power-sensitive video applications.
The THS7365 is available in a TSSOP-20 package
